Abstract: A method for processing carbonaceous material in a reactor. Carbonaceous material, such as sawdust, plant residues from forestry or agricultural processes, municipal solid waste and refuse derived fuel, is fed into the riser section (10) of a reactor (10 - 15) in which it is contacted with inorganic particulate material and reactor walls at an elevated temperature essentially in the absence of oxygen in order to convert the carbonaceous material at least mainly into gaseous processed products, whereby a gas phase is obtained, containing fluidization gas and processed products. According to the invention a dense suspension is formed into the riser space (10) of the reactor, containing based on the particle number 7 x 10 to 3 x 10 particles/m (about 2 x 10 - 1 x 10 particles/ft ), and the mass ratio between the par t iculate matter bringing heat into the reactor and the carbonaceous material is in the range of 1:1 to 10:1. By the invention, the mixing of the heat transfer medium and the feed is improved, and coarser and less uniform feed can be used than conventionally.

Abstract: Method and apparatus for removing solids from an air stream arriving at a central vacuum cleaner. According to the method, solids are separated from a dust-containing stream of air in two stages, in which case the air stream is first fed into a cyclone (12) in order to separate the coarse solids, whereafter the preliminarily cleaned air stream is fed into a second separator, where the finely divided solids is removed. According to the invention, the second separator used is, instead of or alongside a filter, a multi-inlet cyclone (13). In operation according to the invention, the finely divided solids can be separated effectively without a loss of suction efficiency due to clogging of the filter. Furthermore, the pressure difference of the cyclone is in general smaller than the pressure difference across a clean filter, and thus there is even initially more suction efficiency available.

Abstract: A process and apparatus for catalytically converting hydrocarbons to light olefins with a short contact circulating fluidized bed reactor system. The process comprises the steps of feeding a hydrocarbon feedstock into a reaction zone (1) containing a solid catalyst, contacting the hydrocarbon feedstock in the reaction zone (1) with the catalyst under conditions which favour catalytic conversion of hydrocarbons into light olefins, separating the reaction products obtained from the reaction zone (1) after catalytic conversion, recovering the catalyst, and regenerating the deactivated catalyst in a regenerator (3). According to the invention, the hydrocarbon feedstock is contacted with the catalyst in a circulating fluidized bed reactor (1) at a residence time in the range of 0.1 to 3 seconds. The process is used for preparing propylene, butylenes and pentenes and high octane, low benzene gasoline fraction by catalytic conversion of LGO, HGO, VGO or naphta, using conventional or improved FCC catalysts. The process can also be used for preparing propylene, isobutylene or isoamylene rich products by catalytic dehydrogenation from propane, isobutane or naphta, respectively, using conventional or improved dehydrogenation catalysts for fluidized bed service.

Abstract: The invention relates to a method and apparatus for separating two phases from each other. According to the invention, a stream made up of at least two phases is directed to a separation apparatus, which comprises a separation container (25) and cyclones (26) arranged in the flow direction in parallel and in succession, the cyclones having each an elongate separation chamber wherein the phases are separated from each other. According to the invention, the cyclones used are multi-inlet cyclones (26), the total number of which is at least 10. The stream to be treated is directed to each multi-inlet cyclone (26) in a substantially radial direction. Through the placement of a large number of multi-inlet cyclones in parallel, a purification element resembling a filter is obtained. In comparison to a filter, continuous regeneration takes place in the element, in which case the pressure loss does not increase during operation, since solids do not reduce the cross-sectional area of the flow conduit inside the element.

Abstract: The invention relates to a method of converting hydrocarbons. According to the method, a gaseous or liquid hydrocarbon feed is passed into a circulating fluidized-bed reactor, wherein the feed is converted at a high temperature under the influence of particulate matter kept in a fluidized state, and the converted hydrocarbon products are removed from the reactor in a gaseous phase. According to the invention, a circulating fluidized-bed reactor (1-3; 41-43) is used having an axially annular cross section and being equipped with a multiport cyclone (14, 17; 52, 63) for the separation of the particulate matter from the gas-phase reaction products. The reaction space comprises an intershell riser space (13; 50) formed between two concentrically located cylindrical and/or conical envelope surfaces. The separation of particulate matter from the gas-phase reaction products is performed by means of a multiport cyclone equipped with louvered vanes (14; 63).
